- Replacement of the Dehumidification System in Filter Building at Belmont Water Treatment Plant, Philadelphia, Pa
The dehumidification system is over 15 years old and primarily serves the filter building’s pipe gallery, which is located in the basement. The current dehumidification system is tailor- made/proprietary and is a mixture of parts from various companies. The dehumidification system was non-functioning.
Adcon performed a survey and inspected the existing conditions of Philadelphia Water Department’s (PWD’s) Belmont Water Treatment Plant. Adcon prepared the assessment and basis of design report. Adcon performed engineering design for the replacement of the dehumidification system and related engineering design (HVAC, mechanical, and electrical). The intent of the design was to reduce the presence moisture in the pipe gallery.
Adcon provided engineering design for the installation and operation of a new dehumidification system, including a new dehumidification unit that would maintain the pipe gallery space at, or below 40% relative humidity (RH) (+5% RH). The engineering design included but was not limited to the removal of the ductwork, insulation, structural support accessories, hot water piping, and high-pressure gas piping. The engineering design also included the installation of a new recirculation fan, exhaust fan, heating coil, gravity vent, fire and backdraft dampers, air monitoring stations, insulation, structural support accessories, water piping, high-pressure gas piping, valves, and miscellaneous items.
The electrical engineering design portion of the project involved disconnection and removal of the existing electrical components, including wiring from the existing dehumidification system. Also, Adcon performed the engineering design for the installation and connection of the new dehumidification system. The design also pertained to but was not limited to the wiring to the supply fan(s), exhaust fan(s), recirculation fan(s), sensors (including those in the pipe gallery), motors, and dampers.
Adcon also performed construction administration services for this project.
- City of Philadelphia Northeast Water Pollution Treatment Plant
ADCON performed the electrical engineering and design services required for the renovation of the plant. The existing control system takes the 4-20 ma signal for the 48 inch venturi meter and automatically modulates the speed of the pumps. The local meters provide a signal to the control system for display and recording of the readings. The function and programming of these meters was not changed, but the location and type of meter was upgraded. Nine motor-operated valves were replaced by manual valves, and four motor operated valves and their dp switches were being replaced in kind, eight flow meters were replaced, and a new discharge flow meter was added. ADCON prepared the design drawings and specifications.
